Question

please help in my home work​

Answer 1

Step-by-step explanation:

$( \frac{5}{4} + \frac{ - 1}{2} ) + \frac{ - 3}{2} = \frac{5}{4} + ( \frac{ - 1}{2} + \frac{ - 3}{2} ) \\ \\ ( \frac{5 - 2}{4} ) + \frac{ - 3}{2} = \frac{5}{4 } + ( \frac{ - 1 - 3}{2} ) \\ \\ \frac{3}{4} + \frac{ - 3}{2} = \frac{5}{4} + \frac{ - 4}{2} \\ \\ \frac{3 - 6}{4} = \frac{5 - 8}{4} \\ \\ \frac{ - 3}{4} = \frac{ - 3}{4}$
